Hide Header of DetailsTable in Hierarchy RadGrid

Surander

Hi All,
I have Three level Hierarchy RadGrid.
I have to display the grid all records(master or details table) expended mode.
And its working fine by enabling property of master & detailTables HierarchyDefaultExpanded="true"
But problem is i want to hide the "Header of detailsTables" if there is no child records in any level.
